Special Issue Information

Dear Colleagues,

Recent pioneering research in redox biology has enhanced our comprehension of the role of reactive oxygen species (ROS)-induced oxidative stress in aging, as the deterioration of the cellular antioxidant defense system is a significant contributor to the development of visual impairments such as glaucoma, age-related macular degeneration, and cataracts. Nevertheless, despite a wealth of information demonstrating the role of oxidative stress in the induction of aging-related blinding diseases, the molecular mechanisms involved in the onset of oxidative-induced pathology are poorly understood. Also, the causes for excessive intracellular ROS production and dysregulation of the antioxidant defense system, leading to different types of cell death, like apoptosis, pyroptosis, ferroptosis, and so on, and their connection to ocular pathologies, remain elusive. Thus, there is a need to delineate the molecular mechanisms involved between oxidative stress and cell death types and identify the responsible culprit factors(s) to develop target-based therapeutics.

This Special Issue of Antioxidants will focus on studies on unveiling the molecular mechanism of oxidative stress/aging-induced pathological signaling and identify the involved culprit factors causing onset of ocular pathology for a structured tailored approach to manage or treat oxidative-/age-related blinding disorders.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antioxidants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Photoreceptor/retinal degeneration is the major cause of blindness. Induced and inherited mouse models of retinal degeneration are valuable tools for investigating disease mechanisms and developing therapeutic interventions. This study investigated the potential of the antioxidant resveratrol to relieve photoreceptor degeneration using mouse models. Clinical studies have shown a potential association between thyroid hormone (TH) signaling and age-related retinal degeneration. Excessive TH signaling induces oxidative stress/damage and photoreceptor death in mice. C57BL/6 (rod-dominant) and Nrl−/− (cone-dominant) mice at postnatal day 30 (P30) received triiodothyronine (T3) via drinking water (20 µg/mL) with or without concomitant treatment with resveratrol via drinking water (120 µg/mL) for 30 days, followed by evaluation of photoreceptor degeneration, oxidative damage, and retinal stress responses. In experiments using Leber congenital amaurosis model mice, mother Rpe65−/− and Rpe65−/−/Nrl−/− mice received resveratrol via drinking water (120 µg/mL) for 20 days and 10–13 days, respectively, beginning on the day when the pups were at P5, and pups were then evaluated for cone degeneration. Treatment with resveratrol significantly diminished the photoreceptor degeneration induced by T3 and preserved photoreceptors in Rpe65-deficient mice, manifested as preserved retinal morphology/outer nuclear layer thickness, increased cone density, reduced photoreceptor oxidative stress/damage and apoptosis, reduced upregulation of genes involved in cell death/inflammatory responses, and reduced macroglial cell activation. These findings demonstrate the role of oxidative stress in photoreceptor degeneration, associated with TH signaling and Rpe65 deficiency, and support the therapeutic potential of resveratrol/antioxidants in the management of retinal degeneration.
